Uninstall Oracle Java using the Terminal

Note: To uninstall Java, you must have Administrator privileges and execute the remove command either as root or by using the sudo.

Remove one directory and one file (a symlink), as follows:
  • Click on the Finder icon located in your dock
  • Click on the Utilities folder
  • Double-click on the Terminal icon
  • In the Terminal window Copy and Paste the command below:
          sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
          sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.
